01 - Using a sharp knife, make shallow cuts in the chicken thighs to help the marinade penetrate deeply into the meat.
02 - In a large bowl, whisk together Greek yogurt, lemon juice, vegetable oil, minced garlic, grated ginger, ground cumin, coriander, paprika, turmeric, garam masala, cayenne pepper, and salt until fully combined.
03 - Add chicken thighs to the bowl and coat thoroughly with the marinade. Cover and refrigerate for at least 4 hours, preferably overnight for maximum flavor penetration.
04 - Preheat grill to medium-high heat (approximately 400°F). Lightly oil the grates to prevent the chicken from sticking during cooking.
05 - Remove chicken from marinade, allowing excess to drip off. Place on the preheated grill and cook for 6–8 minutes per side, until nicely charred at the edges and internal temperature reaches 165°F.
06 - Transfer grilled chicken to a cutting board and let rest for 5 minutes to allow juices to redistribute throughout the meat.
07 - Arrange chicken on a serving platter and garnish with fresh lemon wedges and chopped cilantro. Serve immediately while hot.
